Good afternoon, if you meet the requirements for that particular course and you are issued with a certificate of sponsorship then you can proceed to apply for certificate of studies then proceed to student visa application. On student visa can work up to 20 hours per week.

You would have to apply at the school for course and also ask whether they will issue the CAS.
It was a pleasure assisting you today. Take care
